Telephone Number Validator

In most SMS Marketing and mass Calls campaigns, the databases include fixed, cellular, invalid and non-existent numbers. The problems with this is that messages and calls to invalid and non-existent numbers are charged by operators, dramatically impacting the effectiveness of campaigns. That is why carrying out a number validation process prior to sending a campaign is of vital importance. With Go4clients you can verify thousands of records in seconds, from any country, simply by uploading your database and after one click you will receive a report with the information of invalid, non-existent, fixed and mobile numbers, and use only those that  exist and pay for messages and calls that will be delivered.
